strong_con_nodes - set of nodes of a strong connected component

### Calling Sequence

  `ns = strong_con_nodes(i,g)`

### Parameters

- `i`: integer, number of the strong connected component
- `g`: graph list
- `ns`: row vector, node numbers of the strong connected component

### Description

`strong_con_nodes` returns the row vector `ns` of the numbers of the nodes which belong to the strong connected component number `i`.

### Examples

    ta=[1 1 2 2 2 3 4 4 5 6 6 6 7 7 7 8 9 10 12 12 13 13 13 14 15];
    he=[2 6 3 4 5 1 3 5 1 7 10 11 5 8 9 5 8 11 10 11 9 11 15 13 14];
    g=make_graph('foo',1,15,ta,he);
    g('node_x')=[197 191 106 194 296 305 305 418 422 432 552 550 549 416 548];
    g('node_y')=[76 181 276 278 276 83 174 281 177 86 175 90 290 397 399];
    show_graph(g);
    ncomp=strong_con_nodes(3,g);
    n=g('node_number');
    nodecolor=0*ones(1,n); nodecolor(ncomp)=11*ones(ncomp);
    g('node_color')=nodecolor;
    nodediam=20*ones(1,n); nodediam(ncomp)=40*ones(ncomp);
    g('node_diam')=nodediam;
    x_message('Set of nodes of the strong connected component #3');
    show_graph(g);
